The Arria V PCIe hard IP operates independently from the core logic. This independent operation allows
the PCIe link to wake up and complete link training in less than 100 ms while the Arria V device completes
loading the programming file for the rest of the device.
In addition, the PCIe hard IP in the Arria V device provides improved end-to-end datapath protection using
ECC.
External Memory Interface
This section provides an overview of the external memory interface in Arria V devices.
Hard and Soft Memory Controllers
Arria V GX,GT, SX, and ST devices support up to four hard memory controllers for DDR3 and DDR2
SDRAM devices. Each controller supports 8 to 32 bit components of up to 4 gigabits (Gb) in density with
two chip selects and optional ECC. For the Arria V SoC devices, an additional hard memory controller in
the HPS supports DDR3, DDR2, and LPDDR2 SDRAM devices.
All Arria V devices support soft memory controllers for DDR3, DDR2, and LPDDR2 SDRAM devices, QDR
II+, QDR II, and DDR II+ SRAM devices, and RLDRAM II devices for maximum flexibility.
Note: DDR3 SDRAM leveling is supported only in Arria V GZ devices.
